PINNATE PRAIRIE CONEFLOWER
Ratibida pinnata, commonly known as Gray-headed Coneflower or Yellow Coneflower, is a tall, stately North American native that is a hallmark of the tallgrass prairie. It is easily recognized by its distinct flowers: drooping, sulfur-yellow petals surround a prominent, grayish-green central cone that eventually turns a dark chocolate brown as it matures. Reaching heights of 3 to 5 feet, its airy, branched stems and deeply lobed green foliage provide a rugged yet graceful vertical element to the late summer garden.
For its ideal spot, Ratibida pinnata is a "workhorse" for full sun locations. It is exceptionally adaptable and thrives in a wide range of soil types, from heavy clay to dry, rocky ground, provided it has decent drainage. Its deep taproot makes it incredibly drought-tolerant once established. Because of its height and tendency to sway in the wind, it is best planted in groups where it can support itself or toward the back of a prairie-style border. Maintenance is very low; the seed heads are a favorite of goldfinches and should be left standing through the winter to provide a food source and architectural interest.
